This invention relates ,to improvements in looms and it is the general object of the invention to provide a loom which 'may be readily convertible from an automatic weft replenish-I ing loom operating with a plurality of weaving shuttles to a loom opera-ting pick and pick with drop boxes on both ends and capable of accommodating a larger number of shuttles.

The class of goods which a textile mill is called upon to manufacturemay vary considerably as to the variety of weft, the simpler fabrics calling for a comparatively small number of shuttles, in which case it is expedient to operate the loom automatically, and the fancier fabrics calling for atlarger number of shuttles which cannot conveniently be replenished automatically by simple mechanism. It has been necessary heretofore to maintaina section of automatic looms to weave the simpler fabrics and maintain a second section of. looms having drop boxes on both ends, to weave the fancier fabrics. It is an important object of my present invention to provide a loom having the automatic weaving instrumentalities in place when weaving simple box patterns, but capable of being swung to inactive position on the loom to permit the addition of drop boxes at the magazine end of the loom. The magazine is mounted so that it can be thrown up to a position where it will not interfere with the shifting of the shuttle boxes adjacent thereto.

The magazines of weftreplenishing looms ordi 'narily include in their construction a foot to be bolted or otherwise secured to the loom breast beam, and furthermore, there is usually a brace between the top of the magazine and the loom arches to prevent undue vibration. It is a further object of my present invention to modify the top brace so that it can be used as a pivot about which the magazine can be swung to inactive position when the loom is converted from automatic to non-automatic pick and pick.

'When the loom is weaving automatically the magazine is generally located with a portion thereof nearer the center of the loom. than the adjacent ends of the arches. It is another object of my invention to provide a brace preferably so constructed as to permit an endwise sliding of the magazine away from the center of the loom so that'the arches will not interfere with the magazine as the latter is pivoted to idle position.

With. these and other objects in view which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth.

Fig. 6 is a detailed vertical section on line 6-6 of Fig. 1, and l Fig. '7 is a detail plan in the direction of arrow 7, Fig. 5.

Referring to the drawings, I have shown a loom which is adapted for weaving either 4x1 or 4x4, that is, four boxes at one end and one at the other, or four boxes at each end, although the invention is not limited to the specific number of shuttle boxes set forth herein. The magazine is of the customary multicolor type and follows a construction which has gone into general use, being arranged to store four distinctive types of reserve weft bobbins which are drawn when needed. for insertion into a selected depleted shuttle.

As shown in Fig. 1 the loom frame to supports a lay H having reed l2 and supported on swords it which move about a rocker shaft 84. The left end of the lay is provided permanently with a set of shifting shuttle boxes it having a plurality of cells, four in number in the present instance, and indicated at l6, ll, l8 and it, re.- spectively. These shuttle boxes may be positioned with respect to the shuttle race of the lay by means of a box lifter rod 2! moved vertically by a chain 22 the position of which is determined by a pattern mechanism such as a Knowles head, not shown but well understood. A picker stick 23 is employed to pick from the left hand side of the loom as viewed in Fig. 1

any shuttle which is aligned with the shuttle race when the lay is approximately in mid position during its rearward travel. The left end of the loom may be of usual construction and of itself forms no part of my present invention.

The right end of the loom is modified so that it can accommodate either a single shuttle box, or four shifting boxes, as desired. The lay has a lay end which as shown in Fig. l is provided with a single shuttle box B formed preferably of a T-section 3|, see Fig. 3. The shuttle S rests on the web 32 as a box floor and is limited as to rearward motion relatively to the lay by a box back 33 formed as part of the section 31. The box back aligns with the reed [2 while the web 32 aligns with the shuttle race 29. The box 3| is held detachably to the lay-endby bolts 34. The web 32 may be provided with a slot 35 to permit discharge of a depleted bobbin from the shuttle S.

The magazine M has inner and outer plates 49 and 4i, respectively connected together by tie rods 42. Provision is made on the adjacent surfaces of the plates 49 and M for the storing and downward feeding of a plurality of distinctive reserve bobbins, four in the present instance to correspond to the cells of the shifting boxes l5. A transferrer arm 43 and latch 44 operate in the usual manner to move a selected bobbin from the giveways to the shuttle.

The magazine has a foot 45 which is mounted on a stand 46 the vertical web 41 of which is bolted at 48 to the loom frame. The web 41 and bolts 48 permit a limited vertical adjustment of the magazine so that the giveways 49 and 50 which support a selected bobbin for transfer may be adjusted relatively to the shuttle S when the lay is inforemost position. vThe magazine is indicated semi-diagrammatically and there has been omitted from the drawings the selector and indication storing mechanism. The weft detector D may be used as indicated in Fig. 5 and is mounted on a support 52 depending from the magazine. I i

For further details of the magazine and the weft detector referencemay be had .to. Patent No. 1,030,748 to Ryon and No. 1,777,346 to'Berg strom.

My present invention includes an .alteration in the upper part of the magazine involving the addition of two links .60 having their forward ends pivoted and held fast with respect to one of the tie rods 42 by means of set screws 6!, see Fig. 5. The other ends of the links are pivoted to swing about a brace rod 62 the inner end of which is supported by the forward arch 63 of the loom and the outer endof which is extended through the .upper end of a brace 64. The lower end of the latter is bolted as at 65 to a carrier 66 forming a fixed part of the loom structure, and as set forth in Fig. 4, supplying one of the bearings 61 for the top shaft 68 which drives the lay. As shown in detail in Fig. 6 the arch 63 is provided with a slot ll! extending horizontally and affording a horizontal adjustment for the position of rod 62, the adjustment being held by a lock nut H. By the construction last described the rod 62 can be moved toward or from the front of the loom when it is necessary to adjust the magazine in that direction to place the magazine correctly for transfer purposes. Slots 53 in foot 45permit a back and forth adjustment of the magazine relatively to the loom, bolts 54 holding the adjustment.

The rear part of the loom frame carries a support 15 having a hook 76 at the forward end thereof which as shown in Fig. 5 is positioned to engage the foot 45 of the magazine and prevent forward motion thereof to the left toward the lay from the dotted line position shown in Fig. 5.

Whenthe magazine is in use in the full line position shown in Fig. 5, it will supply the selected reserve bobbin in the usual manner to permit transfer to the shuttle S which happens to be exhausted and on the magazine side of the loom in the single shuttle box 3|. Under these conditons the loom operates as does an ordinary 4x1 bobbin changing loom, the old bobbin being expelled through the slot 35 and the new bobbin being inserted into the shut-tle. 66 and the rod 62 supported by the arch 63 and brace 64 assist in positioning the upper part of the magazine When it is desired to move the magazine to an inoperative position the bolts 54 are removed so that the magazine may be slid along the rod 62 away from the center of the loom to the dotted line position of Fig. 1, after which the magazine is swung around rod 62, clearing the arches, to the dotted line position shown in Fig. 5. The magazine will come to rest with the foot 45 as already described resting on the support 15 and against the hook l6. Thereafter, as the loom is operated non-automatically the magazine will be held behind the lay, being supported at the front end by the links 60 which are suspended from the rod 62, and at the rear end by the velement'lS. During the sliding of the magazine along rod 62, the foot 45 rests on the stand 46 to support the magazine until the latter is ready to be swung rearwardly.

The purpose of swinging the magazine to the position shown in Fig, 4 is to permit the use at that end of the loom of a second gang of shuttle boxes designated generally at 80 and employing four shuttle cells each having its binder 8|. A shuttle pressurerelieving mechanism indicated generally at 82 may be employed, this mechanism operating generallyalong the principles set forth in Santon Patent No. 2,025,906 and being constructed more specifically as shown in co-pending application Serial No. 59,253 filed by Darwin. a V a In order to adapt the lay for theuse of the gang .of boxes Bl] I employ a plate 85 bolted as at 86 to the lay end 30 and having a groove 87 to receive a tongue 88 on thegang 89. A similar plate 89 having a groove 90 may be located permanently to the lay at the inner end of the gang 89-, or at the left as viewed in Fig. 2. It is to be understood that when the loom is operating automatically as set forth in full lines in Figs. 1 and 5, plate 85 will not be on the lay since the upwardly extending horn 92 thereof would interfere with the rear part of the magazine as the lay beats forwardly.

The links The gang of boxes 89 is mounted on a box rod in Figs. 2 and 5 so that the lowest cell aligns with the shuttle race20. A rod 99 depends from a horizontal ledge I09 of the lay end 30 and extends through a finger ill! on the sleeve 96. 'A coil spring I02 is interposed between a collar I03 on rod 99 and finger llll, acting at all times to 7 prevent the sleeve from risingand during upward shifting of the boxes arresting overthrow of the boxes under the influence of chain 98.

As shown in Fig. 5 the gang of boxes 80 can assume their highest position without interfering with the magazine due to the fact that the support rod 62 around which the magazine pivots is far enough to the rear so that the tops of plates 49 and 4| lie behind the shuttle boxes when the lay is in the rear position, as indicated in dotted lines, Fig. 5. The mechanism for lifting the gang 89 may be of the usual construction, and of itself is not new. c

When the parts are as shownin Fig. 4 the loom operates non-automatically pick and pick, the maximum capacity being seven shuttles and the loom capable of weaving a fabric having a single pick of a given weft as distinguished from the fabrics woven when the magazine is operative wherein at least twosuccessive picks of a given color must be woven due tothe single shut- -tle box 3|.

When the 100m is to be reconverted for automatic weaving the rod 95 together with the gang 80 of shuttle cells, is lifted upwardly out of the loom, the chain 98, however, remaining attached to the sleeve 96 and the rod 99 together with the spring I02 acting in normal manner. The relation of parts is such that even should the chain 98 move in response to pattern chain indications there will be no resultant interference because the chain and the parts operated thereby lie behind the spent bobbin can I 05, shown in' Fig. 3, and are below the bobbin chute 06 down which the expelled bobbins move from the slot to the can I85. In this way a considerable part of the mechanism which operates the gang of boxes 89 can be left on the loom when the latter is operating automatically.

From the foregoing it will be seen that I have provided simple means whereby a loom may be used either to operate automatically with a magazine to supply reserve bobbins, or non-automatically to weave a more elaborate pattern calling for shifting shuttle boxes at both ends of the lay. It

' will also be seen that when the magazine swings from operative to idle position it is clear of all parts of the lay, especially the shifting boxes 80 when the latter are in highest position. It will be seen that the plate 85 is readily removable when the loom is converted from pick and pick to automatic, thereby avoiding interference with the rear part of the magazine as the lay beats forwardly. Again, it will be seen that the removal of the gang 88 together with its rod 95 permits the retention of the chain 98 and sleeve 96 which are located behind the bobbin can H15, in which position movement of the chain 98 will cause no damage. Also', the support 15 is so constructed that the hooked ends 16 thereof sooperates with the foot 45 to prevent movement of the magazine forwardly or to the left from the dotted position shown in Fig. 5 to a position where it might interfere with the lay as the latter swings rearwardly. It should be lnoted that the means employed to support the upper part of the magazine as the latter swings from one to the other position also allows 'both vertical and horizontal adjustments of the magazine relatively to the lay when the loom is operated automatically.

Having thus described my invention it will be seen that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed, but What I claim is:
